Bolin knew both of the two, having met the both of them while passing out fliers the week before. He was definitely happy that they'd both shown up, though all things considered, he was definitely heavy on the firebenders. Really, it was the waterbenders that were less disposed to probending, even if they could be found. He could only hope to show up.

"Nezha, good to see you. And you too, Yang! Glad you could both make it!" He greets them both with a hearty grin, as if it were the best day to make their acquaintances. He pauses for a moment, looking over his notebook and scrunching his forehead. "You're both firebenders, right? Hmmm... how about I see what the both of you have? One versus one, in a fight to the death!!" He pauses, still grinning before realizing what he said; clearly Bolin has had a few too many life-threatening fights of late. "Well, maybe not exactly death... but make it a good match. Only one of you can make it on the team, after all!"
